Kim Kardashian sizzles in post-pregnancy photoshoot as she poses with Khloé and Kourtney to launch new clothing line

Kim Kardashian is back to her glamorous best in her first official post-pregnancy modelling pictures. Posing for the camera in a slinky black dress that clings to her curves, the reality star flaunts her toned figure just four months after welcoming her daughter North.

In another picture, 32-year-old Kim showcases a red lace dress as she poses with her sisters Khloé, 29, and Kourtney, 33. The trio were photographed by Terry Richardson for their new Kardashian Kollection for London clothing brand Lipsy, which launches in the UK on Thursday.

It's not the first time the Kardashian girls have brought their sexy signature style to the British high street; last year they released two hugely successful ranges for Dorothy Perkins.

This new collection draws upon all three sisters' individual style, from Kourtney's boho approach to Kim's glam elegance and Khloé's rock chic look.

"Kim, Khloé and I are always looking for new ways to keep our collection unique and give fans around the world fashion-forward pieces," Kourtney said of the collaboration.

"Whether you are rocking the feathered jacket or one of the leather dresses, there are a million ways to style these pieces, all uniquely stylish," Khloé added.

The range features sequinned biker jackets, crop tops and lace overlay jumpsuits, with many of the prints, colours and fabrics that are signature to the Kardashians' wardrobe also incorporated into the collection.

"The collection is inspired by the stylish women from around the world that I've had the pleasure of meeting," Kim said. "This is for those Lipsy girls who have as much fun with fashion as I do."
